Dinosaur Mystery Solved


Gizmo

Recommended Posts

Not only do Lee and colleagues provide a complete portrait of Deinocheirus based on the new remains, they also find Garudimimus and Beishanlong close relatives of Deinocheirus, necessitating use of the name Deinocheiridae to accommodate all Deinocheirus-like ornithomimosaurs. Since Deinocheirus lacks the features of ornithomimids, would the original describers have known that Deinocheirus was superficially similar to ornithomimids in arm proportions, since megalosauroids went extinct by the middle Cretaceous (keep in mind that all the Asian ornithomimosaurs were not yet known at the time that Deinocheirus was named)?
